Lightweight construction test facility

A new, unique platform for the investigation of sound transmission in lightweight structures. Four rooms can be assembled using lightweight construction techniques for the measurement of direct and indirect acoustic transmission in the horizontal, vertical and diagonal directions. Investigation of other structures, for example stair bedding etc. can be readily undertaken. The lightweight structures test facility is operated and financed in collaboration with the Department of Architecture, Wood and Civil Engineering of the Bern University of Applied Sciences (BUAS), Biel. The facility began operation on  30. Juni 2011.
